R-alpha: R 0.50.a1 suggestion

[Kurt Hornik]

Could we introduce a library hierarchy in the `data' directory?  The
standard stuff would then go into `data/base', and if add-ons have their
own data (examples!), these would go into a corresponding subdir of
`data'.

Only three small changes would be necessary:

1. In `data', create a `base' subdir and move all data files there.

2. Replace `cmd/filename' by the version below:

*********************************************************************
#!/bin/sh

for file in $HOME/lib/R/$1/$2 \
            $RHOME/$1/$2 \
            $RHOME/$1/[^.]*/$2;
do
    if [ -r $file ]
    then
	echo $file
	break
    fi
done

if [ ! -r $file ]
then
    echo
fi
*********************************************************************

3. In src/library/LIBSETUP.in, add

*********************************************************************
        if test -d ${lib}/data
        then
                mkdir -p ../../data/${lib}
                cp ${lib}/data/* ../../data/${lib}
        fi
*********************************************************************

before the final `done'.

We've been using the above filename script for a very long time now,
without any problems ...

Please ...
